16GB DDR4-2666 ECC RDIMM for servers

This 16GB DDR4 2666 ECC Registered RDIMM targets administrators expanding memory in compatible HPE servers. The module uses a 2Rx8 organisation and operates at 1.20V with PC4-21300 speed. It is built with major-brand DRAM from Samsung, SK Hynix or Micron.

Verify 288-pin DDR4 slot and registered support

Before ordering, confirm the server accepts 288-pin DDR4 registered DIMMs and that the memory controller supports ECC registered modules at 2666 MT/s. The platform must also be able to address 2Rx8 density. Mixing registered and unbuffered DIMMs is not supported.

Steady throughput under continuous workloads

Under sustained load the registered buffer reduces electrical loading on the memory bus, helping maintain signal integrity across all populated slots. ECC corrects single-bit errors in real time, preventing data corruption during long-running compute or virtualisation tasks. The 1.20V operation keeps thermal output consistent over extended periods.

Questions about this item

Does the module ship alone or with any accessories or heatsinks?

The module ships as a single 288-pin DDR4 RDIMM; no heatsink, tray or extra cables are included.

I see only one capacity listed — are there other densities or rank options for this part number?

P02890-B21 is offered only as a 16 GB 2Rx8 module; other capacities carry different HPE part numbers.

Will the rated 2666 MT/s transfer rate actually run at that speed in my server?

The module operates at 2666 MT/s when the platform supports DDR4-2666; otherwise it downclocks to the highest speed the memory controller allows.
